Neuron

class brainrender.actors.neurons.Neuron(neuron, color=None, alpha=1, neurite_radius=8, soma_radius=15, invert_dims=True, name=None)

Bases: Actor

Actor representing a single neuron’s morphology.

Methods

make_actor(mesh, name, br_class)	Construct an Actor from an existing mesh.
make_label(atlas)	Create 3D label actors anchored to this actor's mesh.
make_silhouette()	Create a silhouette actor outlining this actor's mesh.
mirror(axis[, origin, atlas])	Mirror the actor's mesh across the given axis.

Attributes

center	Return the mesh's centre of mass coordinates.
labels
silhouette

property center: ndarray[tuple[Any, ...], dtype[float64]]

Return the mesh’s centre of mass coordinates.

Returns:

Array of shape (3,) with (x, y, z) coordinates.

Return type:

numpy.ndarray

classmethod make_actor(mesh, name, br_class)

Construct an Actor from an existing mesh.

Parameters:

• mesh (Mesh) – Mesh to wrap.

• name (str) – Actor name.

• br_class (str) – Brainrender class type.

Return type:

Actor

make_label(atlas)

Create 3D label actors anchored to this actor’s mesh.

Parameters:

atlas (BrainGlobeAtlas) – Atlas used for hemisphere queries and mirroring.

Returns:

Label actors (text and optional sphere markers).

Return type:

list of Actor

make_silhouette()

Create a silhouette actor outlining this actor’s mesh.

Returns:

Silhouette actor with brainrender class "silhouette".

Return type:

Actor

mirror(axis, origin=None, atlas=None)

Mirror the actor’s mesh across the given axis.

Accepts Cartesian axes ('x', 'y', 'z') or anatomical plane names ('sagittal', 'vertical', 'frontal'). If an anatomical name is used without an atlas, 'asr' space is assumed. The mesh is updated in place.

Parameters:

• axis (str) – Axis or anatomical plane to mirror across.

• origin (ndarray[tuple[Any, ...], dtype[TypeVar(_ScalarT, bound= generic)]] | None) – Centre of the mirroring operation. Default None.

• atlas (BrainGlobeAtlas | None) – Atlas used to resolve anatomical axis names. Default None.

Return type:

None
